LDS Church President Russell M. Nelson closed the Sunday afternoon session of general conference by announcing that 12 temples would be built around the world, including one in Washington County.

It will be the second temple in the county — the first is in St. George — and the 20th in Utah for The Church of Jesus Christ of Latter-day Saints.

Nelson, 94, also said pioneer generation temples, specifically Salt Lake City's, would be renovated. He said more details would be shared later. The St. George LDS Temple, completed in 1877, falls into the pioneer generation category. It was rededicated in 1975 after extensive remodeling.

In earlier remarks, Nelson reiterated that he wants members, the media and others to use the church's full name, saying nicknames are "a major victory for Satan."

"When the Savior clearly states what the name of his church should be, and even precedes his declaration with, 'Thus shall my church be called,' he is serious," Nelson said. "And if we allow nicknames to be used and adopt or even sponsor those nicknames ourselves, he is offended."

The faith had embraced and promoted the term "Mormon" over the past several years, using it in a documentary and TV and billboard ads. A church webpage that was up before Nelson's announcement had described the term as an "unofficial but inoffensive nickname for members."

If people use "Mormon" to describe the church or its members, Nelson on Sunday urged adherents to "be courteous and patient" in their efforts to correct them.

Nelson, who in January took over the top post of the Utah-based faith with 16 million members worldwide after the previous president died, rejected what he called "worldly arguments," including the benefits of internet search engine optimization with the word "Mormon."

The faith believes that God revealed the full church name to founder Joseph Smith in 1838. The term "Mormon" comes from the church's signature scripture, the Book of Mormon, which followers believe is based on the record-keeping of an ancient prophet named Mormon.

The entry about the church in the Associated Press Stylebook, which many news outlets follow, remains unchanged.
